Population justification: The population is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: The species's population is suspected to be stable as is not thought to have suffered from habitat loss and there is no evidence that it is susceptible to predation by invasive species.
